21 century life policy

Hi

Please note that I used to be a 21st century funeral policy holder. I have asked them more than 6 times to cancel my policys of which they agreed. They promised to send me forms to cancel of which they haven't. They are still debiting my account more than 6 months later. I keep having to reverse the funds. This is affecting my credit score negatively. Please help me. I have spoken to numerous of there consultants with no success. They charge ridiculous amounts and offer bad service. Can you please help me to make them do the right thing. I am so ****ed. Stop debiting my account 21 century
